PERMIT DRAWING OVERVIEW

What This Permit Plan Needs to Communicate

Home additions and remodels can involve several disciplines at once. A footprint expansion may trigger zoning, setback, lot-coverage, foundation, roof, structural, energy, electrical, plumbing, and HVAC requirements. Interior remodels can also require permits when walls move, rooms change use, plumbing is relocated, structural members are altered, or building systems change.

WHAT MAY BE INCLUDED

A Project-Specific Permit Drawing Package

The exact sheets depend on the project, property, local jurisdiction, and the information available at the start of drafting.

PERMIT SCOPE

Existing & Proposed Plans

Existing-condition plan, demolition plan, proposed floor plan, dimensions, room uses, openings, and construction notes.

PERMIT SCOPE

Site & Zoning Coordination

Property layout, addition footprint, setbacks, lot coverage, access, utilities, flood context, and other site constraints.

PERMIT SCOPE

Structural Design Coordination

Foundations, beams, posts, headers, wall removal, floor/roof framing, load paths, and calculations where required.

PERMIT SCOPE

MEP & Energy Coordination

Electrical, plumbing, HVAC, insulation, energy documentation, fixture changes, and equipment coordination where applicable.

WHAT REVIEWERS LOOK AT

Common Permit Issues to Coordinate Early

Existing Conditions

Accurate measurements, photos, and existing plans are essential where new work must connect to an older structure.

Structural Changes

Wall removal, new openings, roof tie-ins, floor changes, and second-story work may require engineering and calculations.

Zoning & Site Limits

Additions can be limited by setbacks, lot coverage, easements, flood zones, septic systems, or height rules.

Energy & Building Systems

New conditioned area or relocated kitchens/baths may trigger energy, electrical, plumbing, and HVAC requirements.

LOCAL REQUIREMENTS MATTER

The Final Scope Depends on the Project Address

Permit requirements can change between cities, counties, states, zoning districts, flood areas, and project configurations. We review the property and available documents before recommending the drawing scope.

WHAT WE NEED FROM YOU

Start With What You Already Have

  • Property address
  • Survey if the footprint changes
  • Existing floor plan if available
  • Field measurements
  • Photos of all affected areas
  • Desired layout or sketch
  • Roof / exterior photos
  • Known structural conditions
  • MEP information if systems change
  • Permit comments if already issued

HOW IT WORKS

From Project Information to Permit Drawings

1

Send the Address & Scope

Share the project address, intended work, survey, photos, sketches, plans, or permit comments you already have.

2

We Review the Requirements

We identify the likely site, architectural, structural, MEP, or professional-review needs for the project.

3

We Prepare the Drawings

The agreed permit package is developed around the project and available source information.

4

You Review the Draft

Confirm the layout, dimensions, materials, and project-specific details before finalization.

5

Permit Review Support

Applicable correction comments within the original scope can be reviewed and incorporated into revised drawings.

REAL PROJECT CONTEXT

Additions and Remodels Need Existing + Proposed Information to Agree

Permit reviewers need to understand both what exists today and exactly what is changing. Site limits, demolition, new floor plan, exterior changes, roof tie-ins, structural load paths, plumbing, electrical, HVAC, and energy requirements all need to coordinate as one package.

WHY SITE PLANS ONLINE USA

Permit-Focused Drawings, Coordinated Around the Actual Project

One team can coordinate the property, drawing package, supporting disciplines, and plan-review corrections within the agreed scope.

WHY IT MATTERS

Existing-Condition Coordination

We develop the proposed design around field dimensions, photos, available plans, and the conditions that must remain.

WHY IT MATTERS

Architectural + Structural Support

Floor plans, elevations, roof changes, foundations, framing, beams, posts, and load paths can be coordinated within the project scope.

WHY IT MATTERS

MEP & Energy Coordination

Projects involving kitchens, bathrooms, conditioned space, or relocated systems can be coordinated with MEP and energy requirements.

WHY IT MATTERS

Permit Correction Support

If the City returns comments, applicable scope-related corrections can be incorporated into the drawing set.

SCOPE & PRICING

What Affects the Final Drawing Package

We price the work around the actual permit scope rather than forcing every project into the same package. These are the most common items that change the drawing effort.

  • Addition size
  • Existing-condition complexity
  • Structural wall removal
  • Roof tie-in
  • Foundation work
  • Kitchen / bath changes
  • MEP scope
  • Energy documentation
  • Site-plan requirements
  • After-the-fact legalization

PERMIT PLAN QUESTIONS

Frequently Asked Questions

Answers to common questions about this project type and the permit drawing process.

1. What drawings are needed for a home addition permit?

A typical package may include a site plan, existing and proposed floor plans, elevations, sections, foundation and framing plans, structural details, MEP information, and energy documentation.

2. Do I need a site plan for an interior remodel?

Not always. A site plan is more commonly required when the building footprint, exterior improvements, access, utilities, or zoning conditions are affected.

3. Can you prepare plans from an existing house sketch?

Yes, provided sufficient measurements, photographs, and existing-condition information are available.

4. Can you prepare plans for a load-bearing wall removal?

Yes. Structural review typically addresses the replacement beam, posts, connections, and load path to adequate support.

5. Can you legalize an existing addition?

After-the-fact permit drawings can be prepared when existing conditions can be documented and the jurisdiction’s requirements are understood.

6. Can you prepare kitchen and bathroom remodel plans?

Yes. Layout changes, plumbing fixtures, electrical, ventilation, structural work, and other permit items can be coordinated.

7. Can you add a bedroom?

Yes, subject to zoning, egress, septic or utility capacity, energy, structural, and local code requirements.

8. Do additions need structural calculations?

They may, especially where new beams, posts, foundations, roof tie-ins, or altered load paths are involved.

9. Can MEP plans be included?

Yes. Electrical, plumbing, and HVAC drawings can be included when required by the project or jurisdiction.

10. Do you handle energy documentation?

Energy-code coordination can be included or coordinated where required, depending on the jurisdiction and scope.

11. Can you work without original house plans?

Often yes, but accurate field measurements and photos become more important when original drawings are unavailable.

12. Can you prepare exterior elevations?

Yes. Elevations can show the proposed addition, roof tie-in, windows, doors, materials, heights, and exterior relationships.

13. Can you revise drawings after plan review?

Yes. Applicable permit-review comments can be incorporated within the agreed scope.

14. Can licensed professional review be coordinated?

Yes, where required and available, subject to the professional’s final review and acceptance.

15. Do you work nationwide?

Yes. Home addition and remodel permit drawings are supported across the United States.
